Given numbers are 783,861,849,658,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 783,861,849,658,992 is 2965101908832.
Find LCM of 783,861,849,658,992 with Prime Factorization
| 2 | 783, 861, 849, 658, 992 |
| 3 | 783, 861, 849, 329, 496 |
| 7 | 261, 287, 283, 329, 496 |
| 261, 41, 283, 47, 496 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 261 x 41 x 283 x 47 x 496 = 2965101908832
Therefore, the lowest common multiple of 783,861,849,658,992 is 2965101908832.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
783 x 861 x 849 x 658 x 992 = 373602840512832
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
783 : 1, 3, 9, 27, 29, 87, 261, 783
861 : 1, 3, 7, 21, 41, 123, 287, 861
849 : 1, 3, 283, 849
658 : 1, 2, 7, 14, 47, 94, 329, 658
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,861,849,658,992, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
861:3x 7x 41
849:3x 283
658:2x 7x 47
992:2x 2x 2x 2x 2x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 373602840512832/(1x126)
LCM = 373602840512832/126
LCM = 2965101908832
Thus, we can understand that the LCM of 783,861,849,658,992 is 2965101908832.
